Send commands (e.g: shutdown, restart) to device - iotagent-ul

Question

Is it possible to send commands to a device using iotagent-ul?

I want to have the ability to manage my device remotely and perform tasks such as shutdown and restart.

Answer 1

Yes, it is possible. You can find here the syntax of the commands sent by the IoT agent for a UL device.

Those commands are sent to the device from the agent each time an "update context" operation is received at the northbound API of the agent, usually from an Orion Context Broker instance that has registered the agent as the context provider for a context entity related to the device. I.e. at Orion you perform an "update context" operation in order to modify some attribute modeling a command (for instance, a "shutdown" attribute), and such "update context" is forwarded to the agent since it is the registered context provider for the entity/device. Then, the agent translates the "update context" operation into the specific UL protocol I've linked to you.
